Hi,
- Linux Ubuntu 07-04, kept up to date
- CPU0: AMD Athlon(tm) 64 X2 Dual Core Processor 4600+
- 2 Hauppage cards
Hauppauge Nova-T 500 Dual DVB-T
cx88[0]: subsystem: 0070:9402, board: Hauppauge WinTV-HVR1100
DVB-T/Hybrid [card=40,autodetected]
cx88[0]: hauppauge eeprom: model=94009
input: cx88 IR (Hauppauge WinTV-HVR110 as /class/input/input3
The remote from the 1100 works fine. The remote from the T-500
(original card), was not supported when I first compiled v4l-dvb in
June. The code I picked up yesterday attempts to do so but fails and
sends 2 lines to the log file every 150msec., very annoying. I had to
patch the code to limit the output generated (patch included; I haven't
coded in C in 15 years, so I didn't do anything fancy, a real patch
should use a counter on a per card basis).
Output:
Sep 1 17:43:28 mytv kernel: [ 19.140000] dib0700: RC Query Failed
Sep 1 17:43:28 mytv kernel: [ 19.140000] dvb-usb: error while
querying for an remote control event.
...
My patch changes this to
Sep 1 22:15:39 mytv kernel: [ 14.888000] dib0700: Infrared Remote
Failed (T-500 dib0700)
Sep 1 22:15:39 mytv kernel: [ 14.888000] dvb-usb: error while
querying for an remote control event.
... 10 times
Sep 1 22:15:39 mytv kernel: [ 16.292000] dvb-usb: error while
querying for an remote control event.
Sep 1 22:15:39 mytv kernel: [ 18.008000] dvb-usb: error while
querying for an remote control event, stopping polling.
We should avoid filling up /var...
